Abstract: Background and Objective: Consumption of water contaminated by the heavy metals can lead to many biological disorders, cancers or even death. The aim of this study was to evaluate the physicochemical quality of well water and boreholes at 2 sites in Lomé (Togo). Materials and Methods: Analysis was made by atomic absorption spectrophotometer (AAS) for metallic trace elements and the molecular absorption spectrophotometer for nitrates. Results: Well and borehole water from the Agoè Sorad site, close to a large garbage dump, are acid. They were polluted with nitrates with concentrations exceeding the WHO standard. The well and borehole waters of the Bè Aveto site, whose soil was sandy than the previous site, was alkaline and have nitrate pollution with concentrations exceeding the WHO standard. The site was subject to metallic pollution with As, Hg, Pb, Cd and Cu with concentrations above their respective standards with the exception of Cu. Conclusion: This study shows that the 2 sites (Agoè Sorad de Bè Aveto) are polluted with nitrates. Regarding the metallic trace elements studied, the waters of the Agoè Sorad site are safe for consumption. This study also shows that there are potential health risks related to exposure to As, Hg and Pb through the consumption of well water and boreholes at the Bè Aveto site. At the end of this study, the results have shown that the site of Bè Aveto is more polluted than the site of Agoè Sorad.
